Twitter lets you reveal a little bit of the running commentary in your brain to the people who may care enough to follow it. At its best, it’s a reminder that we’re all connected, and no matter how you feel, someone out there feels like that, too. In this way it’s the biggest social experiment in human history. It’s a sci-fi plot worthy of Philip K. Dick: “What if a technology made us all slightly telepathic?” Twitter is connecting our brains in ways we don’t fully understand yet.

A good introduction to twitter for people without attention deficit.
